Yes I agree with Robert on the cookies stuff or Google's ability to get data thro. other advanced means.
Take an imaginary case like this. Adwords uses chrome data or data collected thro. other means to serve relevant personalized ads to users. Google's search algorithms pick up clues from these ads served on their SERPS (search engine Result Pages). In this case, Google is right in saying they don't chrome data as it is adwords which uses the data directly while their search algorithms get signals from the ads served on their SERPS.
So, yes they might be telling the truth when they state they don't use chrome data. Google is very clever in stating things diplomatically and in a manner that suggests what they say is always true. :)
